WhiteList Rule Always dropping down to bottom

If this thread topic has been already asked I apologize. I'm using the the pfBlockerng auto rule white list with custom addresses to allow for web viewing. I have insistences where I can't access the website. When I view the LAN rule I see the white list rule has moved down to the bottom of the pfBlockerng blocked rules so I need to place it back to the top. Why won't the rule stay at the top? How can I prevent the rule from moving to the bottom. Any help would be much appreciated.
